Calling all my old school friends

[JOJABOY]

I drove my truck home from the motor pool this afternoon. The garage was empty since my car was at the office and wife was gone...so I pulled into the garage. Five minutes and a Superman change later and I'm heading back out. Only to find green liquid on the garage floor.

So now I realize I have a tiny radiator leak. Anyone got a good (easy) fix. I know ground pepper is said to work but.... Was looking to see what everyone else has in there knowledge cache.

Thanks
